Abstract

L'invention porte sur des systèmes, des dispositifs et des procédés destinés à aider un pilote à faire atterrir un aéronef. Un procédé donné à titre d'exemple comprend la réception de données représentant une capacité d'approche/atterrissage courante de l'aéronef et de données représentant une intention d'approche/atterrissage du pilote ; et la présentation d'un indicateur combiné indiquant graphiquement et simultanément la capacité d'approche/atterrissage courante de l'aéronef et l'intention d'approche/d'atterrissage du pilote sur un dispositif d'affichage de l'aéronef. L'intention d'approche/atterrissage du pilote peut être indiquée graphiquement par l'intermédiaire d'une coopération entre un premier objet graphique de l'indicateur et un deuxième objet graphique de l'indicateur. Le procédé peut indiquer graphiquement une dégradation de système affectant la capacité d'approche/atterrissage courante de l'aéronef avec le même indicateur.
